The practice does not provide for a conclusion within itself, but is for use in conjunction with appearance or physical property tests to follow the accelerated exposure. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It is applicable to tape in roll form when the user observes the precautions detailed within the procedure.
For instance, when repeating this conditioning one might not set the temperature exactly the same or the atmospheric pressure might vary or the purity of the salt might differ from different vendors. Originally approved in This means that a measurement of precision for a physical property test on tape always has as one of its components the inherent variability between tape specimens.
Include no more sample rolls than will displace one fourth of the air volume in the vessel. For example, a given type of tape a speci?
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
It is not intended for use on electrical grade tapes see Test Methods D A number in parentheses indicates the year of last reapproval. NOTE 1—The environment for this practice cannot occur unless the vessel used as the environment container is vented so that pressure differences between the inside and the outside of the vessel can be balanced. Summary of Practice 4.
D Terminology of Packaging and Distribution Environments. There is no present experience to relate this accelerated exposure to responses of tape in applications where the tape is asrm a use stress. The practice does not provide for a conclusion within itself, but is for use in conjunction with appearance or physical property tests to follow the accelerated exposure.
We do not expect this superimposed added variability effect to be great.
It is applicable to tape in roll form when the user observes the precautions detailed within the procedure. It is not intended for use on electrical grade tapes see Test Methods D Use a volume the units will be cubic centimetres of water not less than that obtained by multiplying times d361 the vessel air volume in cubic metres. This reduces salt deposition and crystalline build-up.
It is superimposed on the variability inherent in performance of the subsequent physical property test for which this conditioning was preparatory. This accelerated exposure usually produces an exaggerated change in appearance which would be seen under natural conditions only in abnormal product.
This standard is subject to revision at any astmm by the responsible technical committee and must be reviewed every?
This practice accelerates the natural aging of pressure-sensitive tapes so that the response to the usual physical property tests changes to the same extent as with an exposure to approximately two years of natural aging when compared with the response to tests before aging. These small differences result in slightly different aging of the tape from time to time.
Current edition approved Oct. Use separators that allow free air space around and between the rolls and which are non-hygroscopic. This may c3611 24 or 48 h for some aastm.
ASTM D3611 – 06(2011)
Appearance of normal tape product will usually change only slightly on two years natural aging. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Reagents for Humidity Vessel in Oven procedure 7. Your comments will receive careful consideration at a meeting of the responsible d611 committee, which you may attend.
Link to Active This link will always route dd3611 the current Active version of the standard. A different type of tape could yield data comparable to more or less than that time period. This is like the variability in any test method that we commonly term its precision.
This standard has been aastm for use by agencies of the Department of Defense. Last previous edition approved in as D — 89 It is an effect due to the small differences that occur in performing any step of a process.
ASTM D – 06() – Standard Practice for Accelerated Aging of Pressure-Sensitive Tapes
While this practice was developed using packaging type tapes, its use on other types of tape with similar construction is encouraged.
This solution within the closed vessel both provides and controls the moisture content humidity within the vessel. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Immediately remove the sample rolls from the assembly. An illustration of this can be made with the peel adhesion test.
The extent of change for one physical property should be expected to be different than for another property and so would also relate to different natural aging time. The environment in the vessel is dependent on careful observation of the requirements of loading in relationship to vessel volume and liquid surface area in accordance with Section 7.

This accelerated exposure usually produces an exaggerated change in appearance which would be seen under natural conditions only in abnormal product.
